For decades, iron-fortified rice cereal was the default first food recommended by pediatricians. It was easy to digest, rarely allergenic, iron-fortified, and had a bland taste babies accepted. All of those things are still true.
What changed was our understanding of arsenic exposure. In 2012, Consumer Reports published testing showing significant levels of inorganic arsenic in rice products, including infant rice cereal. Rice plants absorb arsenic from soil and water more efficiently than other grains — it's a feature of rice biology, not a contamination issue. The FDA followed with its own testing and in 2020 set a limit of 100 ppb inorganic arsenic for infant rice cereal.
The AAP's current position: don't rely on rice cereal as the sole or primary grain. Rotate grains to minimize arsenic exposure. Oatmeal, barley, and multigrain cereals are recommended alternatives. Rice cereal in moderation is still considered safe — the concern is about cumulative exposure from frequent daily use, not about occasional servings.
